Bioarchaeological and palaeogenomic portrait of two Pompeians that died during the eruption of Vesuvius in 79 AD
The archaeological site of Pompeii is one of the 54 UNESCO World Heritage sites in Italy, thanks to its
uniqueness: the town was completely destroyed and buried by a Vesuviusâ eruption in 79 AD. In this
work, we present a multidisciplinary approach with bioarchaeological and palaeogenomic analyses
of two Pompeian human remains from the Casa del Fabbro. We have been able to characterize the
genetic profle of the frst Pompeianâ genome, which has strong afnities with the surrounding
central Italian population from the Roman Imperial Age. Our fndings suggest that, despite the
extensive connection between Rome and other Mediterranean populations, a noticeable degree
of genetic homogeneity exists in the Italian peninsula at that time. Moreover, palaeopathological
analyses identifed the presence of spinal tuberculosis and we further investigated the presence of
ancient DNA from Mycobacterium tuberculosis. In conclusion, our study demonstrates the power of
a combined approach to investigate ancient humans and confrms the possibility to retrieve ancient
DNA from Pompeii human remains. Our initial fndings provide a foundation to promote an intensive
and extensive paleogenetic analysis in order to reconstruct the genetic history of population from
Pompeii, a unique archaeological site
Uniparental lineages from the oldest indigenous population of Ecuador: the Tsachilas
Together with Cayapas, the Tsachilas constitute the oldest population in the country of
Ecuador and, according to some historians, they are the last descendants of the ancient Yumbos.
Several anthropological issues underlie the interest towards this peculiar population: the uncertainty
of their origin, their belonging to the Barbacoan linguistic family, which is still at the center
of an intense linguistic debate, and the relations of their Yumbo ancestors with the Inca invaders
who occupied their ancient territory. Our contribution to the knowledge of their complex past was
the reconstruction of their genetic maternal and paternal inheritance through the sequencing of 70
entire mitochondrial genomes and the characterization of the nonârecombinant region of the Y chromosome
in 26 males. For both markers, we built comprehensive datasets of various populations
from the surrounding geographical area, northwestern South America, NW, with a known linguistic
affiliation, and we could then compare our sample against the overall variability to infer relationships
with other Barbacoan people and with other NW natives. We found contrasting patterns
of genetic diversity for the two markers, but generally, our results indicated a possible common
origin between the Tsachilas, the Chachi, and other Ecuadorian and Colombian Barbacoans and are
suggestive of an interesting ancient linkage to the Inca invaders in Yumbo country
Geographies of the COVID-19 pandemic
The spread of the novel coronavirus (SARS-CoV-2) has resulted in the most devastating global public health crisis in over a century. At present, over 10 million people from around the world have contracted the Coronavirus Disease 2019 (COVID-19), leading to more than 500,000 deaths globally. The global health crisis unleashed by the COVID-19 pandemic has been compounded by political, economic, and social crises that have exacerbated existing inequalities and disproportionately affected the most vulnerable segments of society. The global pandemic has had profoundly geographical consequences, and as the current crisis continues to unfold, there is a pressing need for geographers and other scholars to critically examine its fallout. This introductory article provides an overview of the current special issue on the geographies of the COVID-19 pandemic, which includes 42 commentaries written by contributors from across the globe. Collectively, the contributions in this special issue highlight the diverse theoretical perspectives, methodological approaches, and thematic foci that geographical scholarship can offer to better understand the uneven geographies of the Coronavirus/COVID-19. </jats:p
Educational outcomes in extremely preterm children : neuropsychological correlates and predictors of attainment
This study assessed the impact of extremely preterm birth on academic attainment at 11 years of
age, investigated neuropsychological antecedents of attainment in reading and mathematics, and
examined early predictors of educational outcomes. Children born extremely preterm had significantly
poorer academic attainment and a higher prevalence of learning difficulties than their term
peers. General cognitive ability and specific deficits in visuospatial skills or phoneme deletion at 6
years were predictive of mathematics and reading attainment at 11 years in both extremely preterm
and term children. Phonological processing, attention, and executive functions at 6 years were also
associated with academic attainment in children born extremely preterm. Furthermore, social factors,
neonatal factors (necrotizing enterocolitis, breech delivery, abnormal cerebral ultrasound, early
breast milk provision), and developmental factors at 30 months (head circumference, cognitive development),
were independent predictors of educational outcomes at 11 years. Neonatal complications
combined with assessments of early cognitive function provide moderate prediction for educational
outcomes in children born extremely preterm
Californian Science Students' Perceptions of their Classoom Learning Environments.
This study utilised the What Is Happening In this Class (WIHIC) questionnaire to examine factors that influence Californian student perceptions of their learning environment. Data were collected from 665 USA middle school science students in 11 Californian schools. Several background variables were included in the study to investigate their effects on studentsâ perceptions, such as student and teacher gender, student ethnic background and socio-economic status (SES), and student age. Class and school variables, such as class ethnic composition, class size and school socioeconomic status were also collected. A hierarchical analysis of variance was conducted to investigate separate and joint effects of these variables. Results from this study indicate that some scales of the WIHIC are more inclined to measure personal or idiosyncratic features of student perceptions of their learning environment whereas other scales contain more variance at the class level. Also, it was found that different variables affect different scale scores. A variable that consistently affected students' perceptions, regardless of the element of interest in the learning environment was student gender. Generally speaking girls perceived their learning environment more positively than did boys
Developing a Wellbeing Framework for Aboriginal and Torres Strait Islander Peoples Living with Chronic Disease (Wellbeing Study)
Addressing a need identified by Aboriginal and Torres Strait Islander peoples and their primary
healthcare providers, this study developed a Wellbeing Framework for managing chronic disease in
a manner that also supports wellbeing.
Chronic care models that are currently in use usually focus upon the systems, resources and
policies that are required to deliver care. The important roles of culture, spirituality, Country and
family in maintaining health and wellbeing are notably absent from such models.
Re-defining the way in which care is delivered to reflect Aboriginal and Torres Strait Islander
peoplesâ needs and values is essential for improving the accessibility and acceptability of primary
healthcare services.The research reported in this paper is a project of the Australian Primary Health Care Research Institute which is supported by a grant from the Australian Government Department of Health and Ageing under the Primary Health Care Research Evaluation and Development Strategy
Future scenarios to inspire innovation
In recent years and accelerated by the economic and financial crisis, complex global issues have moved to the forefront of policy making. These grand challenges require policy makers to address a variety of interrelated issues, which are built upon yet uncoordinated and dispersed bodies of knowledge. Due to the social dynamics of innovation, new socio-technical subsystems are emerging, however there is lack of exploitation of innovative solutions. In this paper we argue that issues of how knowledge is represented can have a part in this lack of exploitation. For example, when drivers of change are not only multiple but also mutable, it is not sensible to extrapolate the future from data and relationships of the past. This paper investigates ways in which futures thinking can be used as a tool for inspiring actions and structures that address the grand challenges. By analysing several scenario cases, elements of good practice and principles on how to strengthen innovation systems through future scenarios are identified. This is needed because innovation itself needs to be oriented along more sustainable pathways enabling transformations of socio-technical systems
Horseplay, care and hands on hard work: gendered strategies of a project manager on a construction site
The discourse of managerial expertise favours rational analysis and masculine ideals but contemporary management literature also recognises the value of well-being and employee voice in the workplace. Drawing upon narrative analysis of interview data, we share unique insights into the lived experiences of Laura, one female project manager who recently managed a construction site in the Midlands in the UK. In contrast to previous research which indicates that female managers tend to conform to quite a traditional set of gender behaviours, Laura embraces a range of workplace appropriate gendered strategies, such as hard work and horseplay, together with sensitivity and caring. She draws from this mix of gendered strategies in negotiating between two different discourses of construction; one professional and one tough and practical. Her behaviour both reproduces the masculine ideals (through horseplay and heroic management) and opens up possibilities for modernising construction management (by caring). It is this combination of strategies that is at the heart of tacit expertise for Laura. Theoretically, the discussion adds to the development of a more nuanced understanding of management expertise as situated and person specific knowledge that draws on both the explicit and tacit. Specifically, the centrality of gendered strategies beyond the masculine ideals to success on site is highlighted
Changes in undergraduate student alcohol consumption as they progress through university
BACKGROUND:
Unhealthy alcohol use amongst university students is a major public health concern. Although previous studies suggest a raised level of consumption amongst the UK student
population there is little consistent information available about the pattern of alcohol consumption as they progress through university. The aim of the current research was to describe drinking patterns of UK full-time undergraduate students as they progress through their degree course.
METHOD:
Data were collected over three years from 5895 undergraduate students who began their studies in either 2000 or 2001. Longitudinal data (i.e. Years 1â3) were available from 225 students. The remaining 5670 students all responded to at least one of the three surveys (Year 1
n = 2843; Year 2 n = 2219; Year 3 n = 1805).
Results: Students reported consuming significantly more units of alcohol per week at Year 1 than at Years 2 or 3 of their degree. Male students reported a higher consumption of units of alcohol than their female peers. When alcohol intake was classified using the Royal College of Physicians
guidelines [1] there was no difference between male and females students in terms of the percentage exceeding recommended limits. Compared to those who were low level consumers students who reported drinking above low levels at Year 1 had at least 10 times the odds of continuing to consume above low levels at year 3. Students who reported higher levels of drinking were more likely to report that alcohol had a negative impact on their studies, finances and physical health. Consistent with the reduction in units over time students reported lower levels of negative
impact during Year 3 when compared to Year 1.
CONCLUSION:
The current findings suggest that student alcohol consumption declines over their undergraduate studies; however weekly levels of consumption at Year 3 remain high for a substantial number of students. The persistence of high levels of consumption in a large population
of students suggests the need for effective preventative and treatment interventions for all year
groups
